Abstract
A fan testing system comprises an operation computer, a testing module and a tested fan. The tested fan comprises a fan body and a controller. The testing module comprises a storage unit and an execution unit. The storage unit stores a reference range value and standard parameters. The standard parameters include a standard rotating speed control value and a standard rotating speed value. The execution unit sends the standard rotating speed control value to the controller. The controller controls the fan body to rotate according to the standard rotating speed control value, obtains the actual rotating speed value of the rotating fan body, and then sends the actual rotating speed value to the execution unit. The execution unit outputs test successful information to the operation computer to be displayed when judging that the difference value of the actual rotating speed value and the standard rotating speed value is lower than the reference range value and outputs test failure information to the operation computer to be displayed otherwise. The invention further provides a fan testing method.
